Castro Valley: Brazen New Year’s Eve Half Marathon

December 31, 2023 @ 7:30 am - 12:00 pm

<h1 class="tribe-events-single-event-title">Castro Valley: Brazen New Year’s Eve Half Marathon</h1>

For half marathon participants who wish to hike the course and take more than 4.5 hours, we will offer a “Hiker Division” start at 7:30 am. Those starting at 7:30 should carry water as the first and second aid stations might not be 100% up and running, depending on the hikers speed. Hiker starts will not be eligible to win the race or for age group awards, but will be listed as official finishers in the Hiker Division and will still receive finisher medals.

The 5k is entirely on paved trails. The 10k is about 50% paved trails and 50% dirt trails. The half marathon is approximately 30% paved trails and 70% dirt trails.The 5k and 10k will essentially be out and back courses, while the half marathon will basically be a loop.All courses include rolling hills that are mostly runnable.Courses are subject to change due to weather, park requirements, etc.
